d. The ink is then to be strained
through a flannel, put into a bottle with a little brandy at the top,
well corked, and set by for use in a temperate place. A few cloves
bruised with gum arabic, and put into the bottle, will prevent the ink
from getting mouldy; and if some of superior quality be required, white
wine or vinegar must be used instead of water.

INK POWDER. For the convenience of travellers by sea or by land, ink
powders have been invented, which consist of nothing else than the
substances employed in the composition of common ink, pounded and
pulverized, so that it be instantaneously converted into ink by mixing
it up with a little water. Walkden's ink powder is by far the best.

INK STAINS. The stains of ink, on cloth, paper, or wood, may be removed
by almost all acids; but those acids are to be preferred, which are
least likely to injure the texture of the stained substance. The
muriatic acid, diluted with five or six times its weight of water, may
be applied to the spot; and after a minute or two, may be washed off,
repeating the application as often as it is found necessary. But the
vegetable acids are attended with less risk, and are equally effectual.
A solution of lemon or tartareous acid, in water, may be applied to the
most delicate fabrics, without any danger of injuring them: and the same
solution will discharge writing, but not printing ink. Hence they may be
employed in cleaning books which have been defaced by writing on the
margin, without impairing the text. Lemon juice and the juice of sorrel
will also remove ink stains, but not so easily as the concrete acid of
lemons, or citric acid. On some occasions it will be found sufficient,
only to dip the spotted part in the fine melted tallow of a mould
candle, and afterwards wash it in the usual way.

INSECTS. The most effectual remedy against the whole tribe of insects,
which prey upon plants and vegetables, is the frequent use of sulphur,
which should be dusted upon the leaves through a muslin rag or dredging
box, or fumed on a chaffing dish of burning charcoal. This application
will also improve the healthiness of plants, as well as destroy their
numerous enemies. Another way is to boil together an equal quantity of
rue, wormwood, and tobacco, in common water, so as to make the liquor
strong, and then to sprinkle it on the leaves every morning and evening.
By pouring boiling water on some tobacco and the tender shoots of
elder, a str
